when the oscilloscope is working for more than 30 minutes then it happens pretty often that all the signal is displayed at the left edge of the screen, for example, instead of viewing a nice sine signal, I see a vertical line at the left. What may be the problem?
yes, I see the signal at the very left of the screen, just in one vertical line. I have the schematics of the oscilloscope because this model included them into user manual, but I am not sure where I have to have a look.
May be if this is a frecuent problem, someone may give me some tip.
Since the problem occurs after a certain period, you're probably looking at a faulty IC or a bad solder joint/connection somewhere in the timebase section. Although I do work for a Hameg dealer, I don't have a circuit diagram to hand to be more specific, I'm sorry.
